Spavin.^ — When the enlargement is of 

 a bony nature, it is termed hone-spavin ; 

 if a distended vein at the part, hlood- 

 spavin ; whilst inappreciable (though 

 suspected) changes between the bones of 

 the hock-joint give rise to the so-called 

 occult (hidden) spavin. 



Bog-spavin is a loose term, and can be 

 used in connexion with any swelling of 

 the hock. 



Both light and heavy horses are equally 

 subject to spavin. 



It is spoken of as an hereditary disease 

 when of a bony nature. 



Strictly speaking, there is only one 

 kind of spavin, and that is the bony 

 formation, usually showing itself upon 

 the inner and lower face of the hock, 

 just at the head of the large metatarsal 

 (cannon of hind leg) bone. 



The spavin is really the outcome of 

 inflammation attacking the covering of 

 the bone here and the bone itself.
